General desom'p tz'on This machine is of the type shown in the patents to Frederick L. Fuller, Nos. 1,242,170 and 1,394,256, granted on October 9, 1917 and October 18, 1921, respectively; and to Bernis M. Shipley, No. 1,619,796, granted March 1, 1927. Reference. should be made to these patentsfor a complete understand.-

ing of the adding, indicating and normal total-taking mechanisms as, with various changes and additions to be hereinafter described, the parts mentioned, of the machine embodying this invention, are the same as shown and described in said patents.

The machine embodying this invention is designed for factory accounting. It will, generally, be located in the departmental office. \Vhen a job is assigned to an operator, a time slip in duplicate'is inserted in the machine and the following entries made thereon; the date, the time the job was started, the operators check number, the number of pieces given him for operation, and the job number. When the job is finished the time slip is returned to the machine and the time the job was finished is set up, together with the price per hundred pieces, and the number of pieces actually completed. The machine is then operated and'the data just mentioned are printed just beneath the entry made at the beginning of the operation.

The machine automatically multiplies the number of pieces finished, by the rate per hundred, and prints the product, which is the amount due the operator, on the third line. If there is any additional amount'due i the operator for the time necessary to set up the job or for any other reason, such additional amount will be printed on the fourth line upon depression of the proper keys.

It can be seen from the above that this system provides very complete printed information about the entire operation, and these records may then be turned over to the paymaster and the accounting department for their information.

The machine is provided with 18 classification totalizers. Some of the totalizers are selected by keys, known as quantity keys, and they accumulate the multiplicand or number of pieces, while the other totalizers are selected by keys, known as product keys, and they accumulate the products. The keys are arranged in two banks, one bank containing nine product keys and the other bank containing six quantity keys, and three product keys. The bank containing the nine product keys is known herein as the product bank, while the bank containing the six quantity keys and the three remaining product keys is known'as the quantity bank. vThe addition of the multiplicand in a quantity totalizer and of the product in a product totalizer takes place during a single multiplying operation.

It is evident that the machine can be used equally well for registering day-work operations. All that is necessary is to set up the elapsed time in hours and tenths of hours and the rate per hour, whereupon the machine will compute the amount due the operator, add this amount into the day-work product second tained in the machine.

totalizer, and print the entire transaction both on the record strip and the inserted slip. A device for quickly figuring the elapsed time is attached to the machine.

The amount or multiplicand has two decimal places as is usual in cents and dollars keyboards. Means is provided for placing the decimal point in the multiplier, in any one of four places. In the embodiment of the invention as disclosed herein, the largest multiplier that it is possible to use is 99999, while the smallest is .0001. However, these can be varied if desired, and it is not intended to limit the invention to such limitations.

If a product ends in more than two deci mals, resulting in what is herein termed a rough product, the decimals in excess of two are automatically dropped and one is added to the digit in the second position if the amount of the third digit was five or more. The product of .9 .05=.045 (rough product), and in such case the machine automaticalloy drops the 5 and adds 1 in the ecimal order and prints .05 as the finished product.

But, take the example .9 X .06 .054 (rough product), the machine automatically drops the 4 but does not add 1 in the second decimal order, because the number dropped from the third order did not amount to 5, there- This dropping of the superfluous decimals and addition of one in the second position to get the finished or final product, takes place immediately after the rough product is obtained. It is evident that the keys representing the multiplicand should be released before the superfluous decimals are dropped and the one added in the second position, otherwise a wrong result would be obtained as the machine continues to operate-three more cycles being necessary to finish the complete multiplying operation. Mechanism is, therefore, provided for stopping the machine immediately if any one of the amount keys, representing the multiplicand, fails to return to its normal position when released, or if any key is held down in an attempt to manipulate the machine. The machine then remains inoperative until a manual key release is operated to release the depressed keys so that they can return to normal. The opera tion of the machine can then be completed.

The printing mechanism is designed to print the entries mentioned above, with the exception of the date, on a record strip re- A novel device is included in this mechanism operated by a small hand lever, which deyice is capable of disabling the record strip feeding and impression mechanism during adding and multiplying operations. When anyone of the totalizers is cleared it is essential that the total thereon be printed as otherwise it would be keys of the quantity. and product banks.
